Weightlifting collar and addable weight system and method

Abstract

A system for adding weight and clamping a bar, as non-exclusive example, a barbell collar, includes a weighted collar attachable to a clamp. The clamp may include configurations that mate with the weighted collar, for selectively retaining and removing the weighted collar from mate with the clamp.

What is claimed is: 
     
         1 . A system, comprising:
 a clamp for retaining weight on a weightlifting bar;   a weight attachable to the clamp.   
     
     
         2 . A system, comprising:
 a clamp for a bar; and   a weight removably attachable to the clamp.   
     
     
         3 . A method of manufacture, comprising:
 forming a clamp attachable to a bar; and   forming a weight removably attachable to the clamp.   
     
     
         4 . A system, comprising:
 a first jaw forming a first portion of a hollow cylinder;   a second jaw forming a second portion of the hollow cylinder;   a hinge connecting the first jaw and the second jaw;   a guide of the first jaw;   a first latch element connected to the first jaw opposite the hinge; and   a second latch element capable of removably connecting to the first latch element, the second latch element connected to the second jaw opposite the hinge;   wherein the first jaw and the second jaw form the hollow cylinder when the first latch element is connected to the second latch element.   
     
     
         5 . The system of  claim 4 , further comprising:
 a weight configured for removable connection to the guide.   
     
     
         6 . The system of  claim 4 , further comprising:
 a bias for the second latch element;   wherein the bias urges the second latch element to connect to the first latch element when the first jaw and the second jaw are brought together by rotation on the hinge.   
     
     
         7 . The system of  claim 6 , further comprising:
 a weight configured for removable connection to the guide.   
     
     
         8 . The system of  claim 4 , further comprising:
 a first lever connected to the second jaw opposite the hinge; and   a second lever operative opposing the first lever, connected to the second jaw opposite the hinge;   wherein the first lever and the second lever form the second latch element.   
     
     
         9 . The system of  claim 8 , further comprising:
 a weight configured for removable connection to the guide.   
     
     
         10 . The system of  claim 8 , further comprising:
 a hook connected to the second jaw opposite the hinge;   wherein the hook forms the first latch element.
